I just got finished with the brake discs for my project racer. The stock front discs were still in good shape so i cleaned the up and cross-drilled them. My rear disc was shot so i designed a replacement using autocad and laser cut it from a sheet of Stainless steel.

Anyway i have pictures located here: Link and also on my picture page.

I have the drwings for drilling the fronts and the design of the rear which can also be used for drilling the rear disc. If anyone is interested in these drawings just send me an email. my address is in the above link

 

Seems,
That is a pretty good Idea. Have you seen some of the new disk that they have for the newer quads. They look pretty trick. Where I work, we have cnc machines that I could use to do a lot of trick stuff but the machines always seem to be tied up. I think we are about to get a waterjet machine. I can't wait fo that because I will sure make me some cool stuff.
